Old Caz Beer takes over former Block space in Petaluma this summer

Old Caz Beer is set to move into one of downtown Petaluma’s busiest gathering spots, taking over The Block’s former space at 20 Grey Street this summer. The Rohnert Park brewery’s latest step gives Sonoma County drinkers another place to find the brand, this time inside a venue already known for drawing steady foot traffic, rotating food, and a built-in social scene.

The shift lands as The Block prepares to close out its run with Blockfest on May 9. Opened in 2017, The Block grew from a simple food-truck park into a nine-year community staple, adding a pizza oven, barbecue kitchens, and a full bar along the way. Charles “Cody” Hildreth said the next chapter would be handled by people he and his team know and trust, “like family,” underscoring that this is more than a routine tenancy change. It is a handoff of a place with real local identity.

For Old Caz, the Petaluma move looks like a deliberate footprint expansion rather than a wholesale reinvention. The brewery has built its name around Sonoma County energy, food-truck partnerships, and a brewpub model rooted in neighborhood connection. Its current public taproom sits at 1500 Valley House Dr., Suite 110, in Rohnert Park, while the company also points to its original taproom at 5626 State Farm Dr., Unit 17, in Rohnert Park. Old Caz says it already sells beer in cans and kegs across Sonoma County and beyond, so the Petaluma opening should broaden visibility for a brand that has stayed firmly local in both flavor and identity.

That identity reaches back to the road that inspired the brewery’s name. Old Cazadero Road, the steep, winding route connecting Guerneville and Cazadero in west Sonoma County, helped shape the Old Caz story and the rugged, regional tone behind the label. The brewery describes the road as a throwback to old logging routes, a piece of Sonoma history that matches the brand’s homegrown image.

The new Petaluma location also places Old Caz in a space already built around food and gathering. The Block is marketed as a food-truck market that typically hosts two to four trucks per day, which makes it a natural fit for a brewery that already leans on local kitchen partners. For Sonoma County beer fans, the move means one more place to reach the Old Caz lineup, and one more example of a local craft brand extending its reach without leaving its roots behind.
